AbstractA 38-year-old man who had a history of percutaneous coronary artery coil occlusion was admitted to our hospital with chest pain and shortness of breath. His complaint was chest pain, which is typical. ST depressions were observed during the treadmill exercise stress test. Coronary angiography demonstrated the persistence of a coronary arteriovenous fistula and coils in the fistula. Primarily, additional coil placement inside the arteriovenous fistula was decided as the mode of treatment. The coil was first placed inside the arteriovenous fistula and then an attempt was made to detach it. However, it was unsuccessful after four trials and electrical detachment of more than 3 minutes. Finally, a 2.5 × 18-millimetre graft stent was deployed at 20 atmospheric pressure. Electrocardiographic recordings showed bizarre ST segment changes during the electrical detachment of the coil. In this report, we discuss the concealed bizarre electrocardiographic changes that were seen during coronary arteriovenous fistula occlusion.

T Waves

Wellens' syndrome is characterized by an electrocardiographic pattern of T-wave changes associated with a critical stenosis of the left anterior descending artery (LAD), which progresses to an extensive anterior myocardial infarction in the majority of cases. For this reason, its recognition and early treatment are extremely important. We report 2 cases of Wellens' syndrome: an 83-year-old male presenting with ill-characterized chest pain, biphasic T waves in V1-V3 during an asymptomatic period, negative cardiac biomarkers, and a 64% stenosis in LAD with a fractional flow reserve of 0.96 who fared well on medical therapy, and an 67-year-old male with typical angina pain, biphasic T waves in V2-V4 during asymptomatic periods, anterior ST-segment elevation at 2 min of effort during an exercise stress test, positive high-sensitivity cardiac troponin, and an 80% stenosis in the proximal LAD who was submitted to percutaneous coronary intervention which rendered him asymptomatic. The spectrum of Wellens' syndrome is very wide, and knowledge and high clinical suspicion for its diagnosis, especially in its rarest presentation of biphasic T waves, is key to avoiding catastrophic consequences.
